Maestro is slow to launch and frequently crashes. What could the problem be?
There are several possible reasons for this problem.
1) The slow startup could be due to the job database becoming very large. This is mainly a problem for releases prior to Suite 2011. Type the following command to see how many records are in your job database:
$SCHRODINGER/jobcontrol -list all |grep -v "no jobs were found" |wc -l
If this is a very large number, run the following command to delete records for finished or non-active jobs:
$SCHRODINGER/jobcontrol -delete all
You may also want to set the job database cleanup interval to a shorter duration, for example 1 day instead of the default 7 days. To do this, set the following environment variable:
2) The problem could be the graphics driver. Try launching Maestro in software OpenGL mode with the
This option uses software GL emulation, so it may be a bit slow. If Maestro runs successfully without crashing, then it is likely that there is a problem with your graphics card or driver. Check that your graphics driver is the one from the manufacturer and that it is up to date. Also check whether your graphics card supports OpenGL. If not, consider upgrading your graphics card.
3) Frequent crashing could be due to the graphics card in use. We have received reports that certain onboard integrated graphics cards are showing problems with Maestro (and also other OpenGL software). In many cases updating the driver for the card has solved the problem.
If you experience display problems with Maestro (other than license errors) you might consider updating your graphics driver. Please check your system's manufacturer web site (e.g., Dell, HP) and download the latest driver. We recommend that you install our software on an officially supported platform and use Maestro with a dedicated high quality graphics card with quad buffering, such as Nvidia Quadro FX or ATI. For the list of supported operating systems please read the "Hardware and Software Requirements" section of the Installation Guide.
4) If Maestro is started from a networked file system, the slowness to start could be due to network traffic or bandwidth. Maestro loads libraries and resource files during startup, so the speed could also be related to the file i/o speed. Some file systems cache these files, so a subsequent start can be much quicker.
